Specific cases should be reviewed by Infectious Disease Committee prior to enrollment Have active signs or symptoms of acute infection at the time of the baseline visit (V0). Significant trauma or major surgery within 1 month of signing informed consent. Considered in imminent need for surgery or with elective surgery scheduled to occur during the study History of disseminated herpes zoster or disseminated herpes simplex or a recurrent (more than one episode of) localized, dermatomal herpes zoster Have evidence of prior or current tuberculosis infection as assessed by Purified Protein Derivative (PPD), interferon gamma release assay (IGRA) or by history Have evidence of current or past HIV or Hepatitis B infection Have evidence of active Hepatitis C infection Have current, confirmed COVID-19 infection Current or history of Deep vein thrombosis (DVT), Pulmonary embolism (PE), or other thromboembolic events or history of inherited coagulopathies First degree relative with a history of unprovoked venous thromboembolism (i.e. without known underlying cause such as trauma, surgery, immobilization, prolonged travel, pregnancy, hormone use, or plaster cast), which suggests that a participant may be at increased risk of inherited coagulation disorder Any present malignancies or history of malignancy, other than a successfully treated nonmelanoma skin cancer History of any lymphoproliferative disorder such as EBV-related lymphoproliferative disorder, history of lymphoma, history of leukemia, or signs and symptoms suggestive of current lymphatic or lymphoid disease Known or suspected polymorphism in the Cytochrome P450 2C19 (CYP2C19 gene, resulting in classification as a poor CYP2C19 metabolizer). Have renal impairment (eGFR< 60 mL/min, MDRD) Currently on anti-platelet therapies, excluding low dose aspirin One or more screening laboratory values as stated Neutrophils < 1,500 /μL Lymphocytes < 800 /μL Platelets < 150,000 / μL Hemoglobin < 6.2 mmol/L (10.0 g/dL) Potassium > 5.5 mmol/L or <3.0 mmol/L Sodium > 150mmol/L or < 130mmol/L AST or ALT ≥ 2.5 times the upper limit of normal Bilirubin ≥ 1.5 times upper limit of normal unless diagnosed with Gilbert's syndrome LDL >160 mg/dL Vaccination with a live virus within the last 6 weeks and killed vaccine within 4 weeks (except 2 weeks for flu vaccine and COVID vaccine) Be currently pregnant or lactating or anticipate becoming pregnant during the study Male participants able to father children and female participants of childbearing potential who are unwilling or unable to use 2 effective methods (at least 1 highly effective method) of contraception, including abstinence, as outlined in this protocol for the duration of the study and for at least 3 months after the last dose of investigational product Be currently participating in another T1D treatment study Have hearing loss with progression over the previous 5 years, or sudden hearing loss, or middle or inner ear disease such as otitis media, cholesteatoma, Meniere's disease, labyrinthitis, or other auditory condition that is considered acute, fluctuating, or progressive Acute coronary syndrome (e.g., myocardial infarction, unstable angina pectoris) and any history of cerebrovascular disease within 24 weeks before screening; Heart failure NYHA (New York Heart Association) III, NYHA IV ANY of the following conditions at screening: a. Screening 12-lead electrocardiogram (ECG) that demonstrates: i. Clinically significant abnormalities requiring treatment (eg, acute myocardial infarction, serious tachy- or brady-arrhythmias) or indicating serious underlying heart disease (eg, cardiomyopathy, Wolff-Parkinson- White syndrome); ii. Confirmed QT corrected using Fridericia's correction factor (QTcF) prolongation (>450 milliseconds). b.
